HApplication filed September 25, 1919. Serial No. 326,339.

To all whom t may concern:

Be it known that I', CHARLES, H. Far, a citizen of the United States,and a resident of Newark, county of Essex, and State of New Jersey, haveinvented certain new and useful Improvements in Inserts forl Cement orSimilar Floors, of which the following is a specification.

vrlhis invention relates to an improved inN sert for cement or othermastic floors and is adapted to be used for the passage of pipes orsimilar elements through a' floor. There has been considerabledifficulty in a number of trades to provide for the passage of pipesthrough such floors, in that if not carefully done, the opening isclogged and requires the removal of concrete and cement before the pipecan be passed through, or if due care is taken to see that the openingsare properly and adequately aligned, it taires considerable ,of thefloor layers time, and the present invention is designed to provide adevice that can be easily installed, has no intricate parts thereon tobe adjustedyand when in place is substantial enough to 'p imit thelaying of the concrete floor as ordinarily done, and when completedthere is a properly aligned and properly sized openu ing` for a pipe.

The invention is further designed to provide a device of this kindwhich'can be quickly proportioned according to the thickness of thefioor into which it is to be placed, and which provides not only for theproper clearance for a pipe through the floor, but also provides for thesupport of the pipe, if desired, and also for the attachment of floorand ceiling plates without the necessity of 'fastening such floor andceiling plates to the pipe itself.

The invention is illustrated in the accompanying` drawing, in whichshown preferred form of thc invention, in said drawing Figure 1 being avertical section of the device, and Figure 2 a top view of a lowermember of the construction shown in Figure 1.

In said drawing` is the outlined floor, the term Cfloor in thisspecification referring to the cement or other mastic mass that isplaced green or wet into position and is allowed Ato set or dry, thisbeing done by the erection of what is known as centering, on which themass of the floor is supported until it is set sufficiently to permitthe removal of such support or centering.

The insert includes a lower tubular member 11, which has a flame 12which is adapted t0 be placed so that it yis substantially flush withthe bottom face of the floor, which becomes the ceiling of the nextlower compartment. The annular flange 12 is provided with means thatai'e adapted to permit the securing of the lower member in position, andfor this purpose I provide slots 13 or similar recesses so that theinsert can be nailed or otherwise secured in place to the centering, andthe substantially tubular part 11 projects up from the centering tomaintain the position and alignment of the parts that go to make up thedevice.

A sleeve 14, preferably of sheet metal, such as galvanized iron, isplaced around the tubular member 11 and rest-s on the flange 12, thesleeve 14: being made the desired length, according to the thickness ofthe floor, and can be made long enough so that it terminates at the topedge of the floor that is on a level with the wearing surface, or, ifdesired, it can be provided with a top member which, in the form shown,consists of thev tubular part 15 having the flange 1G which is adaptedto be placed substantially 'on a level with the top dressing, such levelbeing shown infdotted outline at 17 in Figure 1.

It will thus be seen that when the top or upper member is used, thesleeve 14- rests against the flanges 12 and 16 and encloses the inner-ends of the tubulai' members, and when the cement or other plasticmaterial is put in place on the centering the alignment and diameter ofthe vopening are preserved.

lf desired,. a suitable floor plate 18 is placed over the pipe, andscrews 19 or other similar means can be employed for securing it to theflange 16. The ceiling plate 2O at the bottom of the insert is placedaround the pipe and is secured to the flange 12, the securing meansillustrated consisting of screws 21 which pass through holes in theceiling plate and through the perforations 22 in the flange of the lowermember ofthe insert.

On the rear face of the fiange l prefer :to place anchors 23, thesebeing usually :made so that they have a slight overhang, `that is,

they are slightly larger at the top than at the bottom, or they can beprovided with suitable irregularities to secure their being held againstwithdrawal from the cement when the cement sets. ln order to localizethe expansion and contraction, and also the support of the pipe,selected, or, if need be, all of the inserts in a length of pipeeXtending through the floors of the building can be supported from theinsert.

Screws 2li are placed through openings, which openings are at an angleto the bore or aXis of the insert, and preferably, for the purpose ofmaking them accessible, open downwardly through the bottom face of theflange 12, and these screws can be screwed in until they engage the pipe25, which is shown in Figure 1 in vits place within the insert, and thussupport the pipe at this point.

ln this insert the finish of both the floor and the ceiling is neat,since there is no securing of the floor and ceilingplates to the pipe,these being secured to the insert, and the usual sliding down of theceiling plates on the pipe, due to shrinkage or for other reasons, isavoided. y

The faces of the flange 12 and also of the flange 16 can be roughened,that is, they can be unfinished or they; can be artificially roughened,if need be, so that there is a goed surface for the binding of thecement to the insert, although the bottom face of the flange 16 can bemade smooth; in other words, the casting can be finished if it is usedon a wood floor.

The upper tubular member 15 usually eX- tends above the floor line.rlhis is desirable in many cases, especially Where outlets in cementfloors in factories are established to permit the passage of water onthe floor, due for instance, either to flushing or t0 the operation ofsprinkler systems, in which case the water-covers the floor only to avery slight extent, and it is prevented by the upper end of the member15 from passing down around the pipe to the floor below.

It will also be evident that in this insert the lower member 11 can benailed or otherwise fastened directly to the centering. lt is notnecessary to cut the centering, and when the centering is removed thereis a flush surface provided on which to place the plaster. of theceiling.

lt will be evident that minor changes can be made in the details ofparts and in the general construction without departing from the scopeof the invention.

I claim:

1. An insert for concrete or similar floers comprising a lower tubularmember with an annular flange at the bottom, said Hange having anchorelements on its top face, an upper tubular member with an annularflange, a metal sleeve between the flanges and encloslaisses ing theinner ends of the members, and means in one of said tubular members forsupporting a pipe, said flange serving as a member forsecuring thesupport on centering so as to withstand the pouring of cement around themember.

2. fin insert for concrete or similar floors comprising a tubular memberhaving an annular flange, slots in the periphery of said flange, andanchors on the rear face of said flanoe, the slots providing means forsecuring the member to a centering so that the member can withstand thepouring of concrete around it, the anchors securing the member in placeafter the concrete sets.

3. An insert for concrete or similar floors comprising a tubular memberhaving an annular flange, the flange having slots in its periphery toprovide for its secure attachment to a centering, inclined perforatiensextending to the inside of the tubular member, and screws in saidperforations and adapted to project therefrom to engage a pipe in theinsert. Y
